    With the development of industry and the requirement of environmental protection, more and more cities have adopted the way of central heating to solve the heating problem. But the central heating system still has the potential to save energy, and if we don't pay attention to saving energy, because the central heating system is larger, the pipeline is longer, waste is also amazing, take corresponding measures to save energy reasonably, the savings are also substantial. For the heating system, energy conservation is not only the fuel conservation, but also the production of heat energy conservation. Both are equally important. This article mainly discusses the energy saving measures in the Heat Exchange station.


    The function of heat exchange station in heating system and its shortcomings at present


    The central heating system of heat exchange station is an important part. The function of heat exchange station is that the Heat Exchange station is the place where the system heating network and heating users connect. It is the intermediate link between the heat source and the heat source that reaches the destination. The Heat Exchange station decides the quality of heat supply, and also plays an important role in improving the heating condition of the heating network system and the heating quality of the heating network system. At present, in the area of central heating in our country, the common shortcomings of heat exchange station are: serious energy consumption in the heat exchange station, output flow of circulating pump and make-up pump in the station, the output flow can not be adjusted automatically according to the change of heating load and pipe network pressure. After the output of the secondary water temperature can not fully meet the heating standards. The lack of modern high-tech data transmission and communication equipment makes the data transmission rate of heat exchange station slow and unstable.


    What are the energy saving measures in the Heat Exchange station 



    1) the waste of energy in the heat exchange station is caused by the shortcomings of the heat exchange station, mainly due to the serious energy consumption. This is because the equipment in the station does not match the equipment in the boiler room. Some heat exchange stations are added later or are secondary heat exchange stations. In this way, because the construction time is not synchronized with the boiler room, it is impossible to install the equipment that exactly matches the boiler room, or the design of the Heat Exchange station is unreasonable, lacks scientific calculation, and the data have errors. On the other hand, the equipment in the Heat Exchange station is old and can not adapt to the increasing heating area, so the heating quality can not be guaranteed. The measures should be taken to design or transform the heat exchange station reasonably so that the equipment to be used in the station can match the equipment in the boiler room as far as possible, and the waste caused by the mismatch of the equipment can be reduced as far as possible.

    2) the output of circulating pump and make-up pump in the heat exchange station can not change with the change of heating load, nor can it change with the change of pipeline pressure. When the heating load increases, the output of hot water is not enough, so that the quality of heating can not reach the standard, heating temperature is low. When the heating load is less, the output of hot water is too much, and cause the waste of heat energy, increased pipe pressure, and even lead to tube burst. A great deal of energy is wasted. Measures that should be taken are the use of automatic adjustment pumps to control and adjust the circulating pump and make-up pump output hot water flow. The output of hot water is automatically adjusted according to the adjustment of heating load and the change of pipe pressure, which not only ensures the quality of heating, but also makes rational use of energy and reduces the waste of heat energy. It also ensures the quality of heating.

    3) because of the lack of modern control system, the data transmission of heat exchange station is not smooth, and the data display and feedback information of heat supply are not timely, which results in waste. Measures should be taken to introduce modern control system, scientific and reasonable control of heat exchange station hot water output, and make-up water, timely grasp the heating data and heating information, to ensure the quality of heating and reasonable energy conservation.


    Use energy-saving equipment to reduce energy consumption



    1) in the central heating system, to reduce the waste of energy, reduce the consumption of energy. First of all, in the design of the heating system, it is necessary to strictly calculate and repeated verification, must all the heating equipment and the boiler room equipment and heat exchanger are fully matched. Secondly, in the operation after put into use, we must choose a scientific and reasonable water circulation in the system, as far as possible to reduce the loss of resistance. In order to reduce the heat loss caused by the resistance of water circulation, the inlet and outlet pipelines of the boiler should adopt a large diameter to reduce the loss caused by the resistance of water circulation; 

    2) control the quality of circulating water. The circulating water in the heating system should be supplied according to the standard, should meet the water quality standard of the boiler, and should ensure the alkalinity of the circulating water. Keeping the PH value in the range of 10-12, ensuring the quality of the circulating water, can prevent the scaling of the supply pipeline network system, keep the alkalinity of the water can prevent the rust of the boiler tube, thus improving the thermal efficiency of the boiler, and keep the alkalinity of the circulating water can reduce the resistance of the water cycle, and also reduce the loss of the resistance of the circulating water; 

    3) comprehensive balance adjustment measures of heating system. To ensure the quality of heating, not only to ensure the heating of the secondary output hot water temperature. At the same time to ensure the balanced heating quality of users. Avoid the imbalance between hot and cold. To ensure the balance of heat supply, the balance adjustment of heating network is a crucial link. The central heating network system has a large distribution range, so the heating parameters at the head and the end of the heating network must change, and the time of heat output will also vary greatly, so the complexity of data collection, transmission, processing and regulation of the heating network will also increase. With the development of modern computer technology and communication technology, there is a technical foundation to realize the balance adjustment of heat-supply network. The heat-supply enterprises should constantly explore and apply new technology and new technology to make the heat-supply system to save energy as much as possible and achieve the goal of energy-saving。 

       Central heating is the basic form of urban heating today and in the future. With the shortage of energy, we must try our best to reduce the waste of energy. Using advanced technology, reasonable equipment and scientific measures to make rational use of resources, rational use of resources is the responsibility of every enterprise, but also an effective way to maximize the use of enterprises, it is our long-term goal to ensure the quality of circulating water in the heat-supply network system and to reduce the energy consumption of the heating system reasonably and to improve the heat efficiency through the reasonable design of the equipment matched with each other, let's work towards this goal。
